Update to spec v1.0.0-rc.0 and BLSv4 (#1765)

Browse Source 
## Issue Addressed

Closes #1504 
Closes #1505
Replaces #1703
Closes #1707

## Proposed Changes

* Update BLST and Milagro to versions compatible with BLSv4 spec
* Update Lighthouse to spec v1.0.0-rc.0, and update EF test vectors
* Use the v1.0.0 constants for `MainnetEthSpec`.
* Rename `InteropEthSpec` -> `V012LegacyEthSpec`
    * Change all constants to suit the mainnet `v0.12.3` specification (i.e., Medalla).
* Deprecate the `--spec` flag for the `lighthouse` binary
    * This value is now obtained from the `config_name` field of the `YamlConfig`.
        * Built in testnet YAML files have been updated.
    * Ignore the `--spec` value, if supplied, log a warning that it will be deprecated
    * `lcli` still has the spec flag, that's fine because it's dev tooling.
* Remove the `E: EthSpec` from `YamlConfig`
    * This means we need to deser the genesis `BeaconState` on-demand, but this is fine.
* Swap the old "minimal", "mainnet" strings over to the new `EthSpecId` enum.
* Always require a `CONFIG_NAME` field in `YamlConfig` (it used to have a default).

## Additional Info

Lots of breaking changes, do not merge! ~~We will likely need a Lighthouse v0.4.0 branch, and possibly a long-term v0.3.0 branch to keep Medalla alive~~.

The `Makefile` in the project contains four targets for cross-compiling:
- `build-x86_64`: builds an optimized version for x86_64 processors (suitable
for most users).
- `build-x86_64-portable`: builds a version x86_64 processors which avoids
using some modern CPU instructions that might cause an "illegal
instruction" error on older CPUs.
- `build-aarch64`: builds an optimized version for 64bit ARM processors
- `build-x86_64`: builds an optimized version for x86_64 processors (suitable for most users).
Supports Intel Broadwell (2014) and newer, and AMD Ryzen (2017) and newer.
- `build-x86_64-portable`: builds a version for x86_64 processors which avoids using some modern CPU
instructions that are incompatible with older CPUs. Suitable for pre-Broadwell/Ryzen CPUs.
- `build-aarch64`: builds an optimized version for 64-bit ARM processors
(suitable for Raspberry Pi 4).
- `build-aarch64-portable`: builds a version 64 bit ARM processors which avoids
using some modern CPU instructions that might cause an "illegal
instruction" error on older CPUs.
- `build-aarch64-portable`: builds a version for 64-bit ARM processors which avoids using some
modern CPU instructions. In practice, very few ARM processors lack the instructions necessary to
run the faster non-portable build.
